Abstract

The invention discloses a GPS (global position system) signal processing method and device. The method comprises the following steps: receiving a GPS signal, wherein the GPS signal comprises a plurality of multi-path signals; obtaining time domain information containing time-delay two-dimensional degrees of freedom, and spatial information containing a propagation direction in the plurality of multi-path signals; calculating first signal parameters of the plurality of multi-path signals by using a super-resolution technique according to the time-delay two-dimensional degrees of freedom and the propagation direction; filtering the plurality of multi-path signals, and separating the plurality of filtered multi-path signals according to the first signal parameters. The GPS signal processing method disclosed by the invention, differentiation and extraction of the multi-path signals are achieved by developing an effective multi-path signal separation technology, and researching and utilizing the multi-channel spatial information; the multi-path signals can be used for reinforcing the signal-to-noise ratio, and therefore, separation and enhancement of navigation signals under the multi-path condition are achieved by developing the effective multi-path signal combination and researching a coherent superposition method.

Description

technical field [0001] The present invention relates to the technical field of GPS communication, in particular to a GPS signal processing method and device. Background technique [0002] The traditional global satellite positioning system receiver adopts a single-antenna design, and its antenna pattern has an upper hemispherical coverage characteristic, but because the multi-path signals reflected by the ground and other ground interference signals generally have a low elevation angle, in order to eliminate these useless interference The signal requires very low elevation and the gain is very low. [0003] Usually, the GPS signal and the interference come in different directions, and the adaptive antenna array is used to form a spatial beam to enhance the signal and suppress the interference. Adaptive antenna array technology adjusts the array weighting coefficients adaptively. The adaptive antenna array uses the spatial characteristics to distinguish signals and interfere...
